“…Similar conclusion has also been drawn by Li et al [32] on Fe 2 O 3 nano-particles. In fact, for low-temperature CO oxidation, Fe oxide is more often used as supports for noble metals such as Pd and Au [33,34]. It is established that the Fe oxide can supply oxygen to the adsorbed CO on the noble metal sites and then improve the activity for CO oxidation of the noble metals.…”

“…Previously, CO oxidation on Pd deposited on iron oxide film (presumably Fe 2 O 3 ) has been studied by Kalinkin et al [37], which suggested that the reaction (3) occurs at the metal/oxide interface. Therefore, the reaction should exhibit a particle size effect.…”

Adsorption of CO and O2 on Pd particles deposited on a well-ordered Fe3O4(111) film was studied by temperature programmed desorption. Scanning tunneling microscopy was used to provide structural information. The results show that CO adsorbed on Pd particles reacts with oxygen of the oxide support and forms CO2. The reaction occurs at the particle/oxide interface and exhibits a particle size effect such that the smaller particles produce more CO2. Oxidation of Pd/Fe3O4 alters the oxide structure due to Pd catalyzed oxygen migration into the film and results in formation of an oxygen reservoir, which favors CO oxidation reaction.

“…Other CO-oxidation studies on Pd/Fe systems like Pd/Fe 3 O 4 core-shell particles [12], Pd/␣-Fe 2 O 3 [13] or evaporated model system [14] showed moderate catalytic activity with T 50 values between 363 K [12] and 453 K [13] as well as a change of the crystal structure during reaction. The model system showed an E a of 136 kJ/mol, decreasing with increasing reduction temperature.…”

a b s t r a c tA series of differently loaded palladium-iron catalysts was prepared by a controlled co-precipitation method of the nitrate precursors, in order to ensure homogeneous Pd particle size-distribution. After characterization of the pre-catalysts by various techniques, different controlled reduction conditions were applied to investigate the interactions within the Pd-iron system, containing reversible and irreversible processes like phase transformations, SMSI, sintering and alloying. Strong indications for the reversible surface decoration of the Pd nanoparticles with iron oxide species via strong metal-support interaction were found by the combined results of DRIFTS, CO-chemisorption, TEM and XPS measurements. This SMSI state was found to be unstable. It was observed independent of bulk phase or palladium particle size. Catalytic CO-oxidation was found to be a suitable test reaction for the study of the phenomenon: higher activity as well as oxidative deactivation of the SMSI state was observed by investigating the lightoff behavior in repeated, temperature-programmed cycles as well as by isothermal measurements. The instability was found to be higher in case of higher Pd dispersion. In addition, bulk properties of the Pd-Fe system, like alloying, were investigated by detailed XRD measurements.
